Very useful and as described, a healthy remedy for back pain, especially for the lumbar area.

Works properly. Sufficient temperature. Wide back grip. Recommended item. Fast delivery in a cardboard box.

Gets really warm. Some other products never gave enough heat. This does. Figment for me is great. You can choose from 1 to 9. The on/off is with a timer, going from 30min to 2 hours. Thinking of buying a 2nd one

The box looks luxurious. That was unexpected. The remote control has a simple structure. Personally, I think it's very good. It's more intuitive than making things complicated and selling them at a high price. Temperature control, timer settings, and power button are all that's needed.
I set the maximum temperature to 9, and it heats up quickly. I'm a bit concerned about durability and electricity costs, but it's not a big problem. You can just buy it again.
I bought this because I often have muscle strain in my waist and legs, and using it at 9 degrees feels just right. Everyone's perception may be different, but in an environment where I go for walks or cycle every day, this level is very hot for me.
I wear Korean size men's pants with a waist circumference of 32 or 34, and even when I wear thick winter clothes over them, they still fit well. That's great.
To accurately identify the heating area, compare it with a basic PC keyboard.
I hope this helps.
There will be washing issues, so I need to find a cover to cover the heating area or find a replacement. That's great.

Very satisfied with this electric heating waist belt. It heats up quickly and provides nice, even warmth for the lower back. The material is comfortable and the belt fits well. Helps a lot with back pain and muscle tension. Easy to use and good quality.
